RE: Value of a Person-Rem

["Ritchie, Bill" <bill.ritchie@cplc.com>]

This question comes up every now and then in the Nuclear Power Industry.
 The most used value of a Person-Rem in the power industry is $10,000
per Rem.  I attended a meeting of plant ALARA Personnel last month and a
show of hands reflected ~70% used this 10K number.
